Recombinant MLL2 Complex gel MLL2 Complex was run on an 10% SDS-PAGE gel and stained with Coomassie blue.
Recombinant MLL2 Complex HTRF activity assay 3. 3 μM H3K4me0 (1-21aa) peptide was incubated with MLL2 Complex in reaction buffer for 3 hour at room temperature. MLL2 Complex was used in a HTRF assay to determine enzyme linearity. Methylated peptide (H3K4me2) was measured using H3K4me2-specific antibody.
Recombinant MLL2 Complex MALDI-TOF activity assay 3. 3 uM H3K4me0 peptide was incubated with 10 nM MLL2 Complex in reaction buffer for 3 hours at room temperature. The reaction product was detected by MALDI-TOF. Single 3. 3 uM H3K4me0 peptide was used as negative control. Catalytic Ability: ~450 turnovers/ enzyme molecule
